Initial testing using benchmarks shows that the majority of the
descriptor pools allocate fewer than 32 descriptor sets worth of
descriptors. This CL reduces the initial size of each pool from 128 to
32 to reduce memory consumption.

Additionally, when a pool is exhausted and a new one is created, the
size of the pool doubles each time, up to a max of 512 descriptor sets
worth of descriptors.   This allows us to aggressively increase the size
of the pools that appear to be very hot and decrease the total number of
pools created.

UtilsVk implements some functionality with draw calls.  Of these draw
calls, clear was accidentally contributing to occlusion query results.

Additionally, the copyImage utility creates its own framebuffer and thus
directly creates a render pass, bypassing ContextVk::startRenderPass.
This change also fixes bugs where occlusion query handling assumed
mRenderPassCommandBuffer to be valid and correspond to the started
render pass command buffer, which is not true for the copyImage render
pass.

From the OpenGL ES 3.1 spec:

11.1.3.11 Validation
It is not always possible to determine at link time if a program object
can execute successfully, given that LinkProgram can not know the state
of the remainder of the pipeline. Therefore validation is done when the
first rendering command which triggers shader invocations is issued, to
determine if the set of active program objects can be executed.

For draws, this CL moves the PPO link operation to ValidateDrawStates()
to generate PPO link failures within ANGLE's validation layer, so we
fail any rendering commands during command validation.

For dispatch, PPOs are linked during Context::prepareForDispatch(),
where the PPO is converted from draw to compute, since that conversion
requires a re-link. This re-link shouldn't fail due to errors that would
have been caught during validation, since the compute shader must have
successfully linked before it can be included in the PPO in the first
place. We don't re-link when converting back to draw, since it's
possible there are validation errors (which we want to catch during
validation of the next rendering command).

Uniform buffer is implemented in two forms:
- If number of ubo used in shader program is low, each buffer will use
  one discrete Metal buffer slot.
- If number of ubo used is large, they will be embedded into one Metal
  argument buffer. Argument buffer is similar to Vulkan descriptor set.
  This is due to limit of number of Metal's discrete buffer slots which
  is only 31 and over half of them are already used by vertex
  attributes, default uniforms, driver uniforms, etc. The downside is
  that whenever a buffer binding is changed, the argument buffer must be
  updated also.

Added empty TransformFeedbackMtl implementation to enable ES3 context
creation on Metal.

The prior script was incorrectly comparing a boolean result with a
number and producing the opposite result: True would be reported as a
failure, and False would be reported as success.

- If BufferMtl is static or large size, don't use shadow copy. Use one
  MTLBuffer and map directly on it.
- If BufferMtl is dynamic and small size, use shadow copy and buffer
  pool of 10 MTLBuffer (s). The MTLBuffer is allocated in shared memory
  in this case (PCI-E memory for example). MTLBuffer in shared memory
  region doesn't need to sync content between CPU and GPU.
- When copyBuffer, if BufferMtl is being used by GPU use blit command to
  do the copy on GPU side.
- Also implemented GL_MAP_UNSYNCHRONIZED_BIT.

FramebufferVk::updateRenderPassDesc() is resetting entire
mRenderPassDesc, which may lose color unresolve attachments. This CL
makes sure that when we toggle depth stencil buffer's read/write access,
we do not reset the whole mRenderPassDesc. Instead we only update the
depth stencil attachment's access.

This reverts commit 499173de.

Original change's description:
> Pass #pragma optimize setting down to compilation.
>
> This will allow us to disable optimizations in the back-end. This can
> be useful both for developers and for ANGLE to disable very slow
> shader compilation on D3D11.
>
> Also apply this pragma to VerifyMaxVertexUniformVectorsWithSamplers.

set_sources_assignment_filter() is considered as a mis-feature
of gn (as it makes it difficult to reason about the BUILD.gn
files individually).

Change libGLESv2.gni in angle to check the platform before
adding plaform-specific source files to "sources" variable.
This will allow removing the global sources assignment filter
from Chromium codebase.
